ASX Announcement – 20 July 2015
FURTHER HIGH GRADE ZINC ASSAYS FROM PORTE-AUX-MOINES
Further assays received from historic drill core at the Porte-aux-Moines VMS
deposit within the Merléac exploration licence.
A number of high grade intersections generated in second hole PAM16
including 19.5 metres @ 6.5% zinc, 1.0% lead, 1.3% copper, 94.5 g/t silver, 1.0 g/t
gold from 301.5 metres (zinc equivalence of 15.3% Zn Eq).
7 metres @ 6.0% zinc, 1.2% lead, 1.6% copper, 133.7 g/t silver, 1.4 g/t
gold from 329 metres (17.5% Zn Eq)
Includes an intercept in excess of 20% zinc equivalent within the broader
mineralised zone 6.5 metres @ 9.3% zinc, 1.9% lead, 1.5% copper, 142.9 g/t silver, 1.4 g/t
gold from 304.5 metres (21.4% Zn Eq)
Work continues to confirm the potential economic significance of the
deposit.
Assays will contribute to the calculation of a 2012 JORC compliant
Resource, planned for completion later this year.
Final drill hole (PAM8) is currently at ALS for assaying.
Variscan Mines Limited (ASX: VAR) is pleased to announce its wholly owned subsidiary Variscan
Mines SAS has received further encouraging base and precious metal assays from sampling of
historic diamond drill core from the Porte-aux-Moines volcanogenic massive sulphide (VMS) deposit
in Brittany, France.
High grade zinc-lead-copper-silver-gold intervals within massive sulphide horizons were recorded in
the second of three historic holes to be sampled. The results continue to confirm the high grade
nature of the deposit and the quality of the previous exploration work completed by the BRGM.
The new assays also provide strong evidence that a robust JORC compliant resource estimate can
be generated for the deposit once further assays are received and additional geological work is
completed.

Recent work and new assays
Recent work by Variscan Mines at the Porte-aux-Moines VMS deposit within the Merléac exploration
licence has included logging and sampling of three remaining surface core holes drilled into the
deposit as part of a nine kilometre programme conducted by the BRGM (Bureau de Recherches
Géologiques et Minières - the French geological survey) during the late 1970s. On 19 May 2015 the
Company announced that it had received assays from ALS Geochemistry for the first of the drill holes
sampled, PAM5 which recorded a number of outstanding, high grade, zinc-dominant, polymetallic
intersections.
The Company has now received assays for the second of the drill holes, PAM16 (Figures 1 and 2)
which was drilled near the centre of known mineralisation, approximately 50 metres up dip and to the
west of the PAM5 intercepts. Within the massive sulphide zone a number of high grade intersections
have been recorded including 19.5 metres @ 6.5% zinc, 1.0% lead, 1.3% copper, 94.5 g/t silver, 1.0 g/t gold from 301.5 metres
7 metres @ 6.0% zinc, 1.2% lead, 1.6% copper, 133.7 g/t silver, 1.4 g/t gold from 329 metres
2 metres @ 5.8% zinc, 1.7% lead, 1.0% copper, 143 g/t silver, 1.9 g/t gold from 348.75 metres
Within the first, thick intersection a higher grade zone has been defined as follows 6.5 metres @ 9.3% zinc, 1.9% lead, 1.5% copper, 142.9 g/t silver, 1.4 g/t gold from 304.5 metres
These intersections can be directly correlated with those recorded in PAM5 and confirm the good
interpreted continuity of the high grade zones in this area.
The zinc equivalence of the high grade intersections in PAM16 are above 15% Zn Eq (Tables A and
C), with calculated values up to 21.4% Zn Eq, continuing to confirm the high grade nature of the
Porte-aux-Moines mineralization, a critical ingredient for the definition of an economic deposit.

The Zinc Equivalent is based on zinc (US$2,000 per tonne), lead (US$1,800 per tonne), copper (US$5,600 per tonne), silver
(US$15 per ounce) and gold (US$1,150 per ounce). The zinc equivalent calculation represents the total metal value for
each metal, multiplied by a price based conversion factor, summed and expressed in equivalent zinc percent per tonne.
These results are exploration results only and no allowance is made for recovery losses that may occur should mining
eventually result. Nevertheless, it is the Company's opinion that all the elements included in the metal equivalents
calculation have good potential to be recovered as is commonly the case for similar VMS deposits worldwide. The zinc
equivalent calculation is intended as an indicative value only.

showing the location of PAM16 (dotted line) and the approximate projected position of
the high grade massive sulphide zones 150 metres below the surface as interpreted by the
BRGM.
As for PAM5, the PAM16 ALS assays are close in value to the original BRGM assays with the new
assays overall generally slightly higher grade (see Zn Eq variance - Table B), confirming the accuracy
and very good quality of the BRGM work. This provides high confidence in the veracity of the BRGM
assays for the remaining nine kilometres of drilling and underground development.

ASX Announcement - 20 July 2015
The final drill remaining to be analysed, PAM8 is now at ALS. PAM8 is located at the eastern end of
known mineralisation (Figure 1) which appears to have good stratigraphic continuity to that defined in
holes PAM5 and PAM16. As recorded in all three BRGM holes, the central area of Porte-aux-Moines
appears to have at least two to three distinct zones of high grade mineralisation strongly suggesting
the presence of a stacked mineralised system commonly found in other VMS deposits world-wide.
Assays for PAM8 are expected to be received shortly and will be used to help finalise verification of
the remaining BRGM assays to assist in the recalculation the Porte-aux-Moines Resource to 2012
JORC standards.
The Company intends commencing resource estimation work once it has received files for the Porteaux-Moines deposit currently stored at the BRGM in Orleans.
Figure 2 - Cross section through the Porte-aux-Moines deposit highlighting the ALS assays in PAM16. The geological
interpretation comes from BRGM reports.
Planned Work
Over the next six months Variscan plans to 1. Re-assay PAM8
2. Access and digitally convert all the hard copy data held by the BRGM for Porte-aux-Moines to
generate a cohesive 3D model of the deposit.
3. Complete sufficient additional technical work, including possible shallow drilling to calculate a
Page | 4
ASX Announcement - 20 July 2015
JORC compliant Resource on the deposit.
4. Complete the VTEM survey over the more prospective parts of Merléac.
5. Possibly complete ground EM surveys over Porte-aux-Moines and to follow up VTEM
anomalies.
6. Commence drilling in and around the Porte-aux-Moines system and possibly regionally to
follow up targets generated from the geophysics.
Yours faithfully

Samples were taken from sawn quarter core stored at the BRGM (Bureau de Recherches
Géologiques et Minières - the French geological survey) core farm in Orleans.
The mineralised core size is NQ .
Sampling boundaries were set according to boundaries defined in former BRGM sampling from
the 1970’s. These were checked and signed off by Variscan geologists.
BRGM sampling was taken at between 0.5 to 2 metre intervals. The Variscan samples were at 0.5
to 1 metre intervals.
Quarter core samples were bagged and sample prepped by the BRGM and then sent to ALS
Geochemistry, Ireland.
Original BRGM samples were from quarter core. The new Variscan samples are mainly from the
remaining quarter of the 1970’s BRGM sampling.
PAM16 was collared and drilled with “PQ” diameter core to a downhole depth of some 50m
before switching over to “HQ” diameter core to 200 m and then to thin wall “NQ” core for the
balance of the hole.
Core was not oriented.
The drill core was stored in plastic trays and was logged for core recoveries. Most mineralised
intercepts recorded >95% recoveries.
PAM16 was logged by Variscan geologists
Details were entered into the geological database
Samples were collected by BRGM personnel, bagged and tagged with unique sample numbers.
Sample numbers were entered against down-hole depths and sent to Variscan geologists
Average weight per sample was around 2kg
Samples were prepared by the BRGM
Samples were dried and crushed to -2 mm
Samples were then split down with riffle box to recover 100 g
The sample splits were pulverized in a hammer mill to -80 µm
Samples were transported to ALS Geochemistry Ireland for analysis
The ALS assay method used for base metals was ME-ICPORE (multi element analysis of base
metal ores and mill products by atomic emission spectrometry using inductively coupled plasma
spectrometer) which uses a highly oxidizing attack designed for high grade sulphides (the sample
is dissolved with HNO3 , KClO4 and HBr and the final solution in dilute aqua regia).
Gold was analysed using a 30 g fire assay and AA finish (AA23). When high grade gold results
were recorded, additional gold assays were completed with fire assay and a gravimetric finish.
(Au-GRA21)
10% of samples were analysed as duplicates for QA/QC control.
Data storage in Excel spreadsheets and GIS database.
Logging and BRGM assay checks against visible sulphide mineralisation completed by Variscan
geologists.
ALS assays checked against BRGM assays from the 1970’s. Overall repeatability between the ALS
and BRGM assays is considered very good for all elements.
BRGM blanks and standards were included within the samples submitted to ALS.
Samples were located within PAM16 by core blocks marking depths down hole.
The PAM16 collar position and downhole surveys were provided by the BRGM.
Projection and recording of data points into the GIS database into the RGF93 system.
Quarter core sampling at a maximum downhole intervals of 1 metre defined by geology and
previous BRGM sampling intervals.
1 to 2 metre sample compositing used for comparison work against the original BRGM samples.
PAM16 was drilled from north to south at a reasonably high angle to the interpreted sub-vertical
to very steeply north dipping mineralisation.
Core angles of sulphide and host rock bedding were consistently high to the core axis throughout
the hole providing a reasonable test through the mineralised zones.
Samples were prepared at the BRGM prep facilities and transported to ALS Geochemistry Ireland
by commercial carrier.
There has been no external audit or review of the Company’s techniques or data.

parties
Merléac PERM (Permis Exclusif de Recherche de Mine, a French exploration licence)
No known impediments for future exploration and development
Last significant exploration in area is believed to have been conducted by BRGM in the 1980s.
VMS potential of the region was recognised by the BRGM who conducted regional stream
sediment programmes during the mid-1970s. The Porte-aux-Moines deposit was discovered in
1975 when follow-up soil sampling and shallow drilling intersected massive sulphides.
Subsequently the BRGM conducted substantial core drilling (+9km) and underground
development on Porte-aux-Moines.
In addition, the BRGM conducted significant mapping, geochemical and geophysical programmes
around Porte-aux-Moines and regionally.
Much of the exploration data is held by the BRGM and will be compiled and assessed by the
Company.
Volcanogenic Massive Sulphide (VMS) deposits
Three full core holes (PAM5, PAM8, PAM16) have been accessed and logged by Variscan
geologists at the BRGM core facility, Orleans.
Original BRGM logs, coordinate/downhole data and assays for PAM16 have been complied by
Variscan geologists.
Additional data for other holes and underground development is to be provided to Variscan by
the BRGM.
No aggregation or high grade cuts have been applied to the data reported
The orientation of PAM16 is considered a reasonable test of the high grade mineralised zones
which appear to dip from sub vertical to very steeply north at the point of intersection by PAM16.
Based on the BRGM interpretation of the mineralised envelops and the core angles of sulphide
layering as recorded by Variscan geologists in PAM16, the average true width of the intersections
is estimated to be around +80 % of the downhole lengths
Diagrams for the Porte-aux-Moines deposit have been taken from published BRGM reports.
All samples taken are published within the report
Much of the previous exploration, mining, metallurgical and hydrological data is currently held by
the BRGM and will be reported by the Company as it is accessed, complied and evaluated.
One further core hole (PAM8) is to be re-assayed at ALS and reported in a similar manner to
PAM5 and PAM16
